COLUMN SHACKLE Filed July 25, 1929 Patented Mar. 18, 1930 rs'r r COLUMN snAoKrE Application filed July 25,

This invention relates to a column shackle. Primarily, the invention is used for setting columns on a new building in the construction thereof and the main object is to provide a construction whereby the sling employed may be readily unfastened from the column from the floor of the building, to thus avoid the necessity of climbing the column in order to cut the sling loose or to otherwise 1 removethe same. By reason of the present invention, the setting of the columns may be accomplished much more expeditiously than according to existing methods and means.

The more specific objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawings illustrating an operative embodiment.

. In said drawings Figure 1 is a fragmentary side elevation of a column showing the invention in use in connection therewith,

Figure 2 is a cross sectional viewtaken on the line 2-2 of Figure 1,

Figure 3 is a plan view of the shackle in connection with a fragment of the sling, parts of the shackle being shown in section to disclose details, and I 0 Figure 4: is an end elevation of the shackle. 3

conventional column such as is used in the construction of buildings is suggested at 10. In the handling thereof into position in buildings during the construction of the latter, a sling 11, usually of metallic wire braces the column and is adapted for engagement at an eyelet 12 with hoisting means. The other end of the sling as at 13, is fastened to the bridge portion of a U-shaped shackle frame 14. A removable pin 15 passes through openings 16 in the arms of the shackle frame 14, and the opposite extremity of the sling 11 is passed through the shackle, bearing against the pin 15 as shown in the drawings, so that the sling cannot be loosened when supported by the hoisting machinery. The pin 15 is provided with an eyelet 17 at one end and at its other end a key 18, for instance a cotter key, is passed through the pin to prevent accidental detachment thereof.

Referring specifically to the drawings, a

1929. Serial No. 381,054..

Arod or anchor member 19 is screw threaded at 20 or otherw-iseconnected to the shackle. A flexible element 21, such as a chain as. shown, has one end fastened to an eyelet'22 of the-rod or anchor 19. Such flexible element 21 includes a ring 23 which is engaged with the eyelets 16 and the flexible element 21 an; ther has links Qand 25, the former the cotter key 18, and the latter having a draw element 26 connected thereto. The draw element 26 may be of any suitable length so that they same may be engaged and operated from the floor of the building.

As a result of the present invention, instead. of climbing a column such as 10 after it is set, in order to release the sling or out it according to present practices, it is simply necessary floor of the building, the pulling action resulting first in extracting the cotter key'18 fromengagement'with the pin 15, then disengaging the pin 15 from the shackle open- I ings 16, whereupon the sling is freed from the shackle. The parts, it will be realized, cannot become lost or misplaced as they are. all carried by the flexible element 21 and the latter is suspended from the eyelet 22 or connected thereby with the shackleframe.

Various changes may be resorted to provided they fall within the spirit and scope of the invention.

I claim as my invention 1. A device of the class described comprising a frame, a pin movably supported by the frame, a locking member normally prevent-f ing detachment of the pin from the frame, and linking means attached to the locking means and pin and operable to first remove the locking means and then remove the pin.

2. A device of the class described comprising a frame, a pin movably supported by the frame, a locking ing detachment of the pin from the frame,

linking means attached to the locking means 7.

and pin and operable to first remove the locking means and then remove the pin, andthe latter means being, anchored on said frame.

8. A device of the class described comprising a frame, a pin det-achably connected with the frame, a locking member normally preto pull the element 26 from the s member normally prevent- Y venting detachment of the pin, a flexible eleinent anchored to the frame and adapted to be drawn, said element having connection with the pin and with the key, whereby the Y 6 key will first be removed, and the pin will k then be removed from the frame. 7 7

4. A device of the class described compris- I 7 ing a shackle vframe, a flexible element conl nected thereto and adapted to be drawn, a 10 pin to close the shackle detachably carried thereby, a key carried by the pin to normally preventdetachment from the shackle, said element having connection with the pin and with the key in order to first remove the key 15 and then remove the pin from the shackle. In testimony whereof I aflix my signature.
